Desired Behavior
Please catch these (the primary as well as the nested) exceptions and print a meaningful error message with the path of the missing socket.
Actual Behaviour
molecule converge is failing probably because the docker socket is missing. The failing due to the missing socket isn't unexpected, but that's triggers a exception and additionally 3 nested exceptions - that's an unexpected behaviour.

Same error on molecule prepare, my Docker Desktop is running fine on macOS. I can run hello-world container without any issue.
docker==6.1.3
molecule==5.1.0
molecule-plugins==23.4.1
Workaround
In Docker's Desktop, Advanced settings, Allow the default Docker socket to be used.
